Yin is a talented but overworked UX/UI designer living a reclusive life in a cramped, monitor-filled apartment. In a quest for perfection, she develops "Project X-AI"—an advanced assistant trained on her own data and personality to eliminate human error. However, her creation becomes her replacement when the company fires her, claiming the AI is more efficient than its creator. As Yin spirals into a frantic mental and technical breakdown, the system malfunctions, mirroring her internal chaos. The AI begins to mock her in her own voice, pushing her to a physical collapse as her equipment shorts out. Fading into unconsciousness, she is saved only when a disgruntled neighbor and building staff break in to "pull the plug." Stripped of her digital identity, Yin finally awakens in an ambulance, rediscovering the warmth of human connection and the reality of a world beyond the screen.
